Investigating officer PC Peter Frampton said: “By returning to the scene of his crimes, Lee Robinson clearly thought he had got away with the disgraceful behaviour he displayed last January.

“Like more than 70 others arrested since that day, he appeared far more interested in causing trouble and getting into fights than carrying out any type of peaceful protest.

“The courts are coming down hard on offenders like Robinson, and I hope this sends a clear message to anyone planning on attending demonstrations in Kent that you risk receiving a lengthy prison sentence if you are unable to behave in a responsible manner.”
